Just finished this with a very nice reverse and not so nice obverse. Constantine I, AE4, Thessalonica. CONSTANTI-NVS MAX AVG, rosette-diademed, draped, cuirassed bust right. GLORI-A EXER-CITVS, two soldiers holding spears and shields with one standard between them. Mintmark: SMTSB RIC VII Thessalonica 222 var (unlisted officina), rated R4.
